Predicción de crecimiento de la tuberosidad maxilar
2011
Este estudio longitudinal ha sido diseñado para determinar una valoración real del crecimiento de la Tuberosidad Maxilar a través de cualquiera de los tres registros clínicos más utilizados hasta la fecha en las consultas de Ortodoncia: modelos de estudio (MODELOS), ortopantomografías (ORTO) y telerradiografías (TELE). Para ello contamos con una muestra de 60 pacientes (26 niños y 34 niñas) entre 7 y 21 años de edad evaluados en función de su edad dentaria en 2 momentos diferentes: en la primera medición los sujetos presentan dentición mixta 1º fase, y en la segunda, unos diez años más tarde, los mismos sujetos presentan dentición permanente. Dividimos la muestra en 2 grupos: el grupo A rep…
Aerosols generation using Er,Cr:YSGG laser compared to rotary instruments in conservative dentistry: A preliminary study
2021
Background In restorative dentistry, the use of high-speed air turbine, which generates aerosols, can be associated with the transmission of airborne diseases. New laser technologies could be useful in reducing the amount of aerosols, but there is a lack of scientific research on this topic. Material and methods This is a descriptive study to analyze the amount of aerosols produced after class I cavity preparation using high-speed air turbine (group 1) and Er,Cr:YSGG laser with two different parameters (groups 2 and 3). Fluorescein dye was incorporated into the coolant reservoir in order to visualize the production of aerosols during each procedure. Tooth preparation was performed in a typo…
Quality of life after upper third molar removal: a prospective longitudinal study
2017
Background Third molar extraction is a very common procedure in Dentistry. The aim of this study was to evaluate the quality of life (QoL) and satisfaction of patients undergoing extraction of an upper third molar under local anesthesia. A second objective was to describe the evolution of self-reported pain measured in a visual analogue scale (VAS) in the 7 days after surgery and its relationship with pre- and intraoperative factors. Material and Methods A prospective longitudinal cohort study was made. Fifty-five patients received a questionnaire assessing social and working isolation, eating and speaking ability, diet modifications, sleep impairment, physical appearance, discomfort at sut…
Intentional replantation for the management of maxillary sinusitis.
2007
AIM: To present a case that emphasizes the importance of the use of intentional replantation as a technique to successfully treat a periapical lesion and an odontogenic maxillary sinusitis through the alveolus at the same time. SUMMARY: This case report presents a patient with odontogenic maxillary sinusitis secondary to periapical disease of a maxillary molar that had previously received root canal treatment. The molar was extracted, with drainage and rinsing of the maxillary sinus. The apices were resected extra-orally, the retrograde cavities prepared with ultrasound and retrograde fillings of silver amalgam placed. The tooth was then replanted. After 2 years, the patient was asymptomati…
Impacted lower third molars and distal caries in the mandibular second molar. Is prophylactic removal of lower third molars justified?
2017
Background The objective of this study was to evaluate the association between the presence of mandibular third molars and the occurrence of carious lesions in the distal aspect of the mandibular second molar. Material and methods A retrospective cohort study comprising 327 lower third molars extracted in the Oral Surgery and Implantology Master's Degree program of the School of Dentistry of the University of Barcelona (Barcelona, Spain) was carried out. A descriptive and bivariate analysis was made. The diagnosis of caries in the second molar and the position of the mandibular third molar were evaluated through panoramic radiographies. Results The sample included 203 patients, 94 males (46…
Chemical composition and bioactivity potential of the new endosequence BC Sealer formulación hiflow
2020
Aim To evaluate in a laboratory setting the effects of Endosequence BC Sealer HiFlow (Brasseler USA, Savannah, GA, USA), a novel calcium silicate-based sealer developed for use in warm canal filling techniques, on human periodontal ligament stem cells (hPDLSCs). Methodology Eluates of EndoSequence BC Sealer HiFlow (BCHiF) (Brasseler USA), EndoSequence BC Sealer (BCS) (Brasseler USA) and AH Plus (AHP) (Dentsply DeTrey GmbH, Konstanz, Germany), were placed in contact with hPDLSCs. The characterisation of the chemical elements of the root canal sealers was assessed using Scanning Electron Microscopy and Energy Dispersive X-ray analysis (SEM-EDX). Inductively Coupled Plasma Mass Spectrometry (I…
Fibromatosis paramandibular infantil. Presentación de dos casos clínicos.
1996
Las fibromatosis de partes blandas constituyen a menudo un problema diagnóstico, especialmente dado en la edad infantil, debido al carácter celular de estos procesos, que pueden inducir a pensar en la existencia de un fibrosarcoma. Presentamos dos casos de fibromatosis orales de partes blandas paramandibulares, comentándose los hallazgos histopatológicos y los diagnósticos diferenciales planteados.
Comparative biological properties and mineralization potential of three endodontic materials for vital pulp therapy: Theracal PT, Theracal LC, and Bi…
2021
Introduction: The aim of this study was to assess the biological properties and mineralization potential of the new Theracal PT (Bisco Inc, Schaumburg, IL) compared with its predecessor Theracal LC (Bisco Inc) and the hydraulic silicate-based cement Biodentine (Septodont, Saint-Maur-des-Fosses, France) on human dental pulp stem cells (hDPSCs) in vitro. Methods: Standardized sample discs were obtained for each material (n 5 30) together with 1:1, 1:2, and 1:4 material eluates. Previously characterized hDPSCs were cultured with the different materials in standardized conditions, and the following assays were performed: a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, a wo…
Relación entre caries y tabaquismo pasivo entre los escolares de 12 y 15 años de la Comunidad valenciana.
2013
Se ha estudiado la prevalencia de caries tanto en dentición temporal (DT) como en permanente (DP) y los valores de los índices CAO.D y co.d de los escolares de la Comunidad Valenciana (CV) teniendo en consideración la variable tabaquismo pasivo dentro del hogar familiar. Se diseñó un estudio transversal descriptivo y analítico en el que se incluyeron escolares de 12 y 15 años en un muestreo representativo por conglomerados. En total fueron 456 escolares de 12 años y 433 escola- res de 15 años, a los que se les realizó un examen intraoral y posteriormente cumplimentaron un cuestionario de hábitos y atención bucodental. En los niños que conviven con un familiar fumador no se han encontrado di…
Aesthetic perception of single implants placed in the anterior zone. A cross-sectional study
2016
Background: Several aesthetic indexes have been described to assess implant aesthetics. The aim of this study was to compare the aesthetic assessment made by dental professionals and students of single-tooth implants placed in the upper incisors. Material and Methods: A cross-sectional survey study using a subjective questionnaire to assess the aesthetics in 3 implant supported single-tooth cases in the anterior maxilla was performed. The interviewed subjects were divided into 4 groups: dentists with experience in implant treatment, dentists without experience in implants and 3rd and 5th year dental students. The questionnaire consisted of 2 visual analogue scales (VAS) to evaluate aestheti…
